Bipartisan coalition warns delays to Renewable Fuel Standard implementation could weaken demand for corn, soybeans and other biofuel feedstocks.
In a rare occurrence of by-partisan unity, a bipartisan coalition of members of the U.S. House of Representatives is pressing federal regulators to maintain strong support for the nation's biofuel industry, arguing that renewable fuel policies play a critical role in farm income, rural jobs and consumer fuel costs.
U.S. Representatives Adrian Smith of Nebraska and Nikki Budzinski of Illinois recently led a bipartisan letter to U.S. Environmental Protection Agency Administrator Lee Zeldin and U.S. Energy Secretary Chris Wright, urging the administration to preserve the integrity of Renewable Fuel Standard (RFS) volume requirements for 2026 and 2027.
The lawmakers are asking the administration to issue a supplemental rule by October 15, 2026, to ensure renewable fuel obligations remain aligned with previously announced targets.
The letter was signed by dozens of lawmakers from major agricultural and biofuel-producing states, reflecting broad support for renewable fuels across party lines. Supporters contend that certainty around future blending requirements is vital for maintaining investment throughout the biofuels supply chain, from crop production and feedstock processing to renewable fuel manufacturing and distribution.
For farmers, the issue extends well beyond energy policy. Biofuel production remains one of the most important sources of demand for agricultural commodities, particularly corn used in ethanol production and soybean oil used in biodiesel and renewable diesel. Industry leaders have long argued that stable renewable fuel policies help support commodity values and encourage investment in rural communities. Similar concerns have been expressed in previous discussions surrounding renewable fuel targets and biofuel demand growth.
According to the lawmakers, uncertainty surrounding Renewable Fuel Standard requirements could weaken market confidence at a time when producers are making planting, marketing and investment decisions. The letter notes that farmers, feedstock processors and biofuel producers responded to previous federal commitments with investments, expansion plans and hiring initiatives, particularly after the administration announced plans related to small refinery exemption volume reallocations earlier this year.
The coalition also stressed that renewable fuels can deliver economic benefits beyond the farm gate. In their letter, lawmakers cited estimates showing E15 gasoline saves drivers an average of 30 cents per gallon compared to E10, while B20 biodiesel is approximately 11 cents per gallon less expensive than conventional diesel fuel. The representatives argued that maintaining established renewable fuel volumes would help preserve those consumer savings while supporting domestic energy production.
Biofuel demand has become increasingly important for U.S. agriculture. Ethanol continues to represent a major market for corn production, while biomass-based diesel and renewable diesel have created growing demand for soybean oil and other feedstocks. Recent federal renewable fuel policies have sought to expand opportunities for advanced biofuels while providing longer-term certainty for producers and investors.
The lawmakers warned that delays in implementing a supplemental rule could undermine the intended benefits of the Renewable Fuel Standard's strongest-ever renewable volume obligations. They argued that uncertainty surrounding volume requirements and small refinery exemptions could weaken incentives for investment across the biofuel value chain and create unnecessary risk for farmers and rural businesses.
As the October 15 deadline approaches, agricultural groups, renewable fuel producers and rural stakeholders will be closely watching federal actions. The outcome could influence demand prospects for key crops, future investment in renewable fuel infrastructure and the overall strength of U.S. biofuel markets in the years ahead.
